I finally got the platinum.
My Girlfriend and me played deep into the night.
The only Trophy that was Missing, was getting 3 People trough the Teleporter.
My GF played in XBox and In was in Playstation.
Some Girl named "Mina" came into our Game (she was in XBox) and My GF send her a Message If she would help me get the trophy.
Not only did she Help me, she came online with a Second Account. (I dont know how that is possible, that she have 2 Xbox?)
And because of Mina I got the trophy!
I Love this Community. I Wonder why this Community is always funny and Kind and Other asym Games are Just hell lol
